Abstract

Shading device for a transparent surface part of a motor vehicle having a flexible shading structure, two non-parallel lateral guide arrangements fixed with respect to the vehicle and having a dimensionally stable pull-out profile displaceable in parallel fashion by in each case one guide carriage in the respective lateral guide arrangement via a drive device, lateral shading structure sections protruding, in a manner dependent on the displacement travel of the shading structure, into lateral receiving spaces fixed with respect to the vehicle. To the lateral shading structure sections, there are fastened in each case two support bodies spaced apart from one another in the pulling-out direction of the shading structure and the thickness of which is greater than a thickness of the respective shading structure sections. The support bodies are guided in transversely supported fashion with play in complementary support channel sections of the receiving spaces.

First claim

The invention claimed is:

1. A shading device for a transparent surface part of a motor vehicle, comprising:
a flexible and rectangular shading structure which can be displaced between a rest position, in which the shading structure is stowed in a compact manner, and a shading position, in which the shading structure covers the transparent surface part in a vehicle interior;
two non-parallel lateral guide arrangements which are fixed with respect to the vehicle and which flank a displacement travel of the shading structure on opposite sides thereof, and which taper towards each other at tops thereof;
a substantially non-flexible pull-out profile which is arranged on a front face end region of the shading structure as viewed in a pulling-out direction;
a transverse guide strip that extends continuously over an entire width of the shading structure transversely with respect to the pulling-out direction, the guide strip connecting the shading structure to the pull-out profile such that the shading structure is not directly connected to the pull-out profile;
the pull-out profile, at opposite face sides thereof, being displaceable in parallel fashion in each case by one guide carriage in a respective one of the lateral guide arrangements by way of a drive which engages on the guide carriage; and
a pair of lateral shading structure sections of the shading structure protruding, in a manner dependent on a displacement travel of the shading structure, into lateral receiving spaces which are configured to be fixed with respect to the vehicle and which are assigned to the guide arrangements;
wherein each of the lateral shading structure sections comprises at least two support bodies which are spaced apart from one another in the pulling-out direction of the shading structure and a thickness of which is greater than a thickness of the shading structure and which are guided in transversely supported fashion with play in complementary support channel sections of the receiving spaces, each of the at least two support bodies on each lateral shading structure section moving along a single line as the shading structure moves between the rest position and the shading position; and
wherein each of the support channel sections of the receiving spaces includes, in cross-section, a pair of elongate opposite aligned walls having an open entrance area at one end of the pair of walls and an end area at the other end of the pair of walls, each of the support bodies moving within the support channel sections of the receiving spaces flanked by the pair of elongate opposite aligned walls between the open entrance area of the support channel sections of the receiving spaces and the end area, with the support bodies moving toward and away from the open entrance area and the end area as the shading structure moves between the rest position and the shading position.

2. The shading device as claimed in claim 1 , wherein guidance of the support bodies with play in the support channel sections is such that sliding of the support bodies in the support channel sections yields virtually no increase in overall friction forces during a displacement of the shading structure between the rest position and the shading position.

3. The shading device as claimed in claim 1 , wherein the support bodies are positioned laterally outside a respective longitudinal edge of the respective lateral shading structure section and are fastened by way of laterally projecting tab or strip sections to the respective shading structure section.

4. The shading device as claimed in claim 1 , wherein the support bodies are integrated into the lateral shading structure sections, each support body being assigned, spaced apart in the longitudinal direction, a complementary cutout in the shading structure, into which cutout the respective support body protrudes when the shading structure is wound up on a winding shaft.

5. The shading device as claimed in claim 1 , wherein the pair of elongate opposite aligned walls are continuous between the open entrance area and the end area.

6. The shading device as claimed in claim 1 , wherein the elongate opposite aligned walls are longer than spaces between the elongate opposite aligned walls at the open entrance area and at the end area.

7. The shading device as claimed in claim 6 , wherein the pair of lateral shading structure sections of the shading structure protrude into the receiving spaces at the open entrance area.

8. The shading device as claimed in claim 1 , wherein the support bodies move within the support channel sections of the receiving spaces along a movement direction line, with the movement direction line extending through the open entrance area.

9. The shading device as claimed in claim 8 , wherein the movement direction line is straight.

10. The shading device as claimed in claim 1 , wherein the pull-out profile comprises at least one sliding guide track extending along the pull-out profile for the transverse guide strip to slide freely therein.

11. A shading device for a transparent surface part of a motor vehicle, the shading device comprising:
a flexible rectangular shading structure displacable between a rest position wherein the flexible shading structure is stowed in a compact manner and a shading position wherein the flexible shading structure is configured to cover the transparent surface part;
two non-parallel lateral guide arrangements flanking the shading structure on opposite sides thereof;
a substantially non-flexible pull-out profile arranged at a front face end region of the flexible shading structure as viewed in a pulling-out direction, the pull-out profile being displacable by a guide carriage connected to each side edge of the pull-out profile; and
at least two support bodies connected to each side of the flexible shading structure and protruding into lateral receiving spaces of the guide arrangements, the at least two support bodies being spaced apart from one another in the pulling-out direction of the shading structure, a body thickness of each of the at least two support bodies being greater than a shading thickness of the shading structure, each of the at least two support bodies being guided within complementary support channel sections of the receiving spaces and each of the at least two support bodies on each side of the flexible shading structure moving along a single line as the shading structure moves between the rest position and the shading position;
wherein each of the support channel sections of the receiving spaces includes, in cross-section, a pair of elongate opposite aligned walls having an open entrance area at one end of the pair of walls and an end area at the other end of the pair of walls, each of the support bodies moving within the support channel sections of the receiving spaces flanked by the pair of elongate opposite aligned walls between the open entrance area of the support channel sections of the receiving spaces and the end area, with the support bodies moving toward and away from the open entrance area and the end area as the shading structure moves between the rest position and the shading position.

12. The shading device as claimed in claim 11 , wherein sliding of the at least two support bodies in the support channel sections yields virtually no increase in overall friction forces during a displacement of the shading structure between the rest position and the shading position.

13. The shading device as claimed in claim 11 , wherein the at least two support bodies are positioned laterally outside longitudinal edges of the shading structure and are fastened to the shading structure by a laterally projecting tab or stri
